At this time, make sure that the handle can be locked in
the lowered position by turning the handle latch. If the
handle cannot be locked so, turn the adjusting bolt so
that the handle can be locked in the lowered position.
CAUTION:
• After installing a new blade, always be sure that the
blade does not contact any part of the lower base when
the handle is lowered completely. Always do this with
the tool unplugged.
Adjusting the miter angle (Fig. 8)
Loosen the grip by turning counterclockwise. Turn the
turn base while pressing down the lock lever. When you
have moved the grip to the position where the pointer
points to the desired angle on the miter scale, securely
tighten the grip clockwise.
CAUTION:
• When turning the turn base, be sure to raise the handle
fully.
• After changing the miter angle, always secure the turn
base by tightening the grip firmly.
Fence plate
The fence plate is designed to prevent smaller cutting
scraps from jamming inside the blade case. The fence
plate moves right or left automatically as the turn base is
rotated.
Switch action (Fig. 9)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
“OFF” position when released.
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop.
WARNING:
• NEVER use tool without a fully operative switch trigger.
Any tool with an inoperative switch is HIGHLY DAN-
GEROUS and must be repaired before further usage.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing saw blade
CAUTION:
• Always be sure that the tool is switched off and
unplugged before installing or removing the blade.
• Use only the Makita socket wrench provided to install
or remove the blade. Failure to do so may result in
overtightening or insufficient tightening of the hex bolt.
This could cause a personal injury.
To remove the blade, use the socket wrench to loosen
the hex bolt holding the center cover by turning it coun-
terclockwise. Raise the blade guard and center cover.
(Fig. 10)
Press the shaft lock to lock the spindle and use the
socket wrench to loosen the hex bolt clockwise. Then
remove the hex bolt, outer flange and blade.
(Fig. 11 &
12)
To install the blade, mount it carefully onto the spindle,
making sure that the direction of the arrow on the surface
of the blade matches the direction of the arrow on the
blade case. Install the outer flange and hex bolt, and then
use the socket wrench to tighten the hex bolt (left-
handed) securely counterclockwise while pressing the
shaft lock.
(Fig. 13 & 14)
CAUTION:
• The inner flange has a 25 mm diameter on one side
and a 25.4 mm diameter on the other. The side with
25.4 mm diameter is marked by “25.4”. Use the correct
side for the hole diameter of the blade you intend to
use. Mounting the blade on the wrong side can result in
dangerous vibration.
Slip the pin on the blade guard into the slot in the guide
arm while returning the blade guard to its original fully
closed position. Then tighten the hex bolt clockwise to
secure the center cover. Lower the handle to make sure
that the blade guard moves properly. Make sure shaft
lock has released spindle before making cut.
(Fig. 15)
Dust bag (Fig. 16)
The use of the dust bag makes cutting operations clean
and dust collection easy. To attach the dust bag, fit it onto
the dust nozzle.
When the dust bag is about half full, remove the dust bag
from the tool and pull the fastener out. Empty the dust
bag of its contents, tapping it lightly so as to remove par-
ticles adhering to the insides which might hamper further
collection.
NOTE:
• If you connect a Makita vacuum cleaner to your saw,
more efficient and cleaner operations can be per-
formed.
Securing workpiece (Fig. 17)
WARNING:
• It is extremely important to always secure the work-
piece properly and tightly with the vise. Failure to do so
can cause the tool to be damaged and/or the work-
piece to be destroyed. PERSONAL INJURY MAY
ALSO RESULT. Also, after a cutting operation, DO
NOT raise the blade until the blade has come to a com-
plete stop.
CAUTION:
• When cutting long workpieces, use supports that are
as high as the top surface level of the turn base. Do not
rely solely on the vertical vise and/ or horizontal vise to
secure the workpiece.
Thin material tends to sag. Support workpiece over its
entire length to avoid blade pinch and possible KICK-
BACK.
